<p><b>BUG ID:</b> <a href="https://bugs.webkit.org/show_bug.cgi?id=43341">Bugzilla bug 43341</a>
Setting canvas width after canvas already rendered resets canvas data appropriately, but doesn't repaint immediately.
<p id="success" style="background-color:palegreen; padding:3px;"><b>TEST PASS:</b>
The canvas should go blank due to setting on the canvas width.
